The Promax HF 2-piece cranks are Promax’s top-of-the-line crank and are Hollow-forged from 6061-T6 aluminum. Both crank arms are hollow so they are super stiff, yet lightweight. The crank arms spin on a beefy 24-millimeter spindle permanently fitted into the drive-side arm.With a 104-millimeter BCD four-bolt spider, they come in a variety for beautiful anodized finishes. Bottom bracket sold separately.
